Embodiment Construction

[0025] Generally, embodiments of the present invention relate to remote monitoring of the health of wind turbine gearbox components in wind energy applications through sensors coupled to wind turbine gearbox components and / or adjacent components, and to methods and systems for supplying power to sensors . The sensors transmit data on wireless communication lines and are provided with electricity from locally harvested energy. In this way, the sensor can be operated indefinitely without wires, cables or other physical connections across the mobile interface. Energy is harvested inductively by mounting the armature to the component and placing magnets so that the armature undergoes a changing magnetic flux due to the movement of the gearbox. Local energy harvesting can allow the sensor to function indefinitely. In a representative embodiment, the monitored component is located in the planetary gear box, but the present invention is not limited to this. Monitoring can include o...

Abstract

Equipment and methods for monitoring the components in the gear box of the power generation system.The gear box includes a gear group with relatively moving components, an agent of a component attached to one of these components, and a magnet that attached to another component in these components.The radio system to undergone a variable magnetic field from the magnet to generate electrical energy.The electrical device for monitoring components healthy is located in the gearbox and power supply from the power from the agent.

Description

Technical field [0001] This application generally relates to power generation systems, and more specifically, to monitoring the health of components in the gearbox of the power generation system, such as wind turbines. Background technique [0002] A practical-scale wind energy system or wind farm includes a group of wind turbines that operate together as power generation equipment to produce electricity without consuming fossil fuels. The wind turbine includes a rotor, a generator, and a gearbox housed in the nacelle, and is placed on a tower located at a sufficient height above the surrounding area, so that the turbine is provided with a stronger and more consistent wind flow than the wind flow at ground level . A megawatt-class wind turbine can have a nacelle weighing more than 100 tons and a rotor with a span of more than 90 meters. Due to their size, weight and working height, performing major repairs on wind turbines is expensive, often requiring cranes to remove the roto...
